Tree of trees
=============

This example shows how to plot trees at the leaf of a tree, using the `iplotx` library.
Note that there are a few conceivable ways to do similar things as this in
`matplotlib` and this is just one such approach, using inset axes.

Combining this with other elements, e.g. cascading backgrounds, is possible too:
